Defence events in the United Kingdom

With European defence budgets at historic highs, programme and portfolio management professionals face acute pressure to deliver capability faster and with greater governance rigour — making this one of the few senior forums specifically dedicated to defence PPM execution rather than technology or procurement. The deliberately small delegate cap (80) means decision-makers — not mid-level attendees — fill the room, creating high-density networking with programme directors and PMO heads who control major delivery budgets. For PPM-tooling vendors, digital-engineering firms, and consulting SMEs, it is a rare access point to the European defence programme leadership tier without the noise of a large trade show.

Concentrated room of NATO end users and dual-use investors. For investors it is curated deal flow; for founders it is a warm introduction to alliance customers.

For defence SMEs and suppliers, IDS is one of the few niche forums where procurement decision-makers, programme offices (including DE&S and allied equivalents), and NATO representatives discuss active capability gaps and acquisition priorities in a small-group setting — making it highly efficient for business development and shaping bids. Co-location with the Uncrewed & Autonomous Systems conference in 2026 broadens the addressable audience to include the fast-growing autonomy and UAS procurement community. The early-bird deadline and tiered partnership packages make it accessible to smaller companies seeking thought-leadership or exhibition exposure alongside primes.

With 250+ senior defence, government, and industry representatives attending, this is one of the UK's most focused annual forums for UGV and UAS procurement discussions, making it a direct channel to British Army, NATO, and allied acquisition decision-makers. SMEs and technology startups can access dedicated exhibition and roundtable partnership slots that place emerging autonomous solutions in front of programme managers and capability developers. The co-location with International Dismounted Soldier amplifies cross-domain relevance for suppliers covering soldier systems, robotics, and human-machine teaming.

Soldier modernisation programs are recurring and broad. A focused venue for firms in wearables, power, optics and edge compute to reach program offices.

Multi-domain coverage and a strong UK/Commonwealth procurement presence make DSEI a primary BD event for firms targeting the UK MoD and allied buyers.
